To (all 117101 7'1 7211/. 7 concern:

Be it known that I, CLARENCE S. LUIT- WIELER, a citizen of the United States, residing at Boston, in the county of Suffolk, State of Massachusetts, have invented a certain new and useful Improvement in Upper-Leather- Piece Markers, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has relation to printing or marking machines of the class in which the printing head is furnished with disks or wheels bearing suitable printing characters upon their peripheries and adapted to be set by rotating them about their respective axes to produce the required combination or arrangement of characters to be impressed or imprinted upon the articles needing to be printed or marked.

In the manufacture of boots and shoes it is customary after cutting out the different portions of leather which when subsequently joined together constitute the upper of a shoe for example, the quarter, vamp, and other pieces to mark them in suitable manner, so as to identify the size, width, &c., of shoe for which they are intended for convenience in subsequently assembling the component parts of an upperthat is to say, for the purpose of enabling in the stitching-room, for example, pieces all intended for one and the same size of upper to be selected by the operative for the purpose of being united together. Usually in practice heretofore the pieces have been marked by hand with crayons of suitable colors after being cut out. Such marking, however, has the drawback that in consequence of the handling to which the pieces are subjected after being marked the crayon-markings become more or less completely effaced. It often occurs that the marking on some pieces becomes wholly removed, and it then becomes necessary in order to identify the size, 620., to return such pieces to the cutting-out room and have them compared with the patterns which were used in their production and again marked. In

cutting out the parts for the uppersof shoes ordinarily the work is done by the case, as it is termed, a prescribed number of shoes of each of a certain range of sizes being provided for. The sizes, respectively, are cut in regular succession, those bearing the lowest number coming first. The widths, hovevcr, may come in a varying sequence.

The illustrated embodiment of my invention has been devised more especially for the purpose of enabling the parts for the uppers of shoes to be marked as or immediately after they have been cut and before having been sent forward to the stitching-room. The said embodiment is provided with a size-wheel and means for rotating the same step by step, so as to present the numbers in consecutive order, a width-wheel havingin connection therewith means whereby it may be set by hand into any position required by the width of the intended shoe to which the piece in hand pertains, and a half-size marker located conveniently adjacent, preferably between, the two wheels and adapted to be thrown into 0perative position by hand whenever required.

For convenience of manipulation the halfsize marker has in connection therewith a coupling device by means of which it is engaged with the size-wheel, so that after the half-size marker has been placed in operative position, as above referred to, when next a change is made in the position of the sizewhcel the half-size marker automatically is thrown into inoperative position out of the way, in readiness, however, to be again set in operative position when next required. It maybe stated in this connection that I have set forth above the leading purpose for which my invention has been devised. The principles of the invention are not, however, necessarily restricted to use in the precise connection stated--to wit, the marking of the pieces for the uppers of shoesfor they may be utilized for other purposes as well, and the number of wheels employed in practice, the nature and significance of the characters on such wheels, &c., may vary.

My invention has relation more especially to the printing-l1ead that is to say, to the printing devices and their carrier.

The precise character and arrangement of the carrier itself and the manner and means of supporting and operating the same form no the stop or detent device coacting therewith.

Fig. 3 shows the printing-head in elevation with the wheel and detent device of Fig. 2 removed and certain parts broken away in order to show more clearly parts which would otherwise be hidden. Fig. 4 is a sectional detail showing more particularly the devices for advancing one of the printing-wheels and the detent devices in connection with said wheel.-

Fig. 5 is a view of the printing-head mainly in horizontal section.

Having reference to the drawings, a portion of the arm constituting the carrier for the printing devices is indicated at 1 in Figs. 1 and 5. At 2, Figs. 1, 2, and 5, is the wheel which in the present instance constitutes the sizewheel. At 3, Figs. 1, 3, and 5, is the wheel which in the present instance constitutes the width-wheel, and at 4:, Figs. 1, 3, and 5, is the half-size marker. The two wheels and the half-size marker are sleeved upon the stud 7 Figs. 3, 4, and 5, with which the carrier 1 is provided and are capable of turning independently around the said stud in order to enable the required characters on the said wheels to be brought into printing position on the carrier and to enable the half-size marker to be swung into and out of the said position as required in the use of the said machine. In the present arrangement the half-size marker is located between the two wheels. (See Figs. 1 and 5.) The size-wheel 2 is furnished around its periphery. with raised characters in the shape of numerals, while the width-wheel 3 is provided around its periphery with radial projections which bear raised characters in the shape of letters. Each of the said wheels is provided also with index characters which-when brought to a certain point by the adjustment of the respective wheels indicate the characters which are in printing position. In the present instance the index characters of size-wheel 2 are numerals corresponding with those on the periphery of said wheel and are located upon one side of wheel 2 near its periphery, while those of width-wheel 3 are letters corresponding with the letters at the periphery of said wheel and are located upon the sides of the radial projections bearing the width characters. The half-size marker is provided with a marking-surface 41, Fig. 3, shaped to produce a transverse line lntervenlng between the size-numeral and the width-letter in the imprint upon the piece which has been marked. Suitable detent devices are provided for the purpose of holding the two wheels from unintended or accidental movement and also for positioning them each time they are adjusted.

In the present embodiment of the invention for these purposes there are provided springpressed pins or bolts, the heads of which are arranged .to enter depressions or holes which are formed in the webs of the two wheels. a circular series of the said depressions or holes being formed in each wheel.

The locking and positioning pin orbolt for the size-wheel is indicated at 8, Figs. 4 and 5. It occupies a socket 9, with which the carrier 1 is provided for its reception and is backed up by a spring 10,,Fig. 5, operating with a tendency to project the said pin or bolt and cause its outer end to enter the hole or recess 12 in the web of the size-wheel, which is presented in position adjacent to the said pin or bolt. The pin or bolt 8 has a beveled acting end, facilitating the entrance of the said end into one of the holes or recesses 12 12, &c., of the size-wheel and also enabling the pin or bolt 8 to be pressed back when sufiicientforce is applied to the size-Wheel tending to rotate the latter. The pin or bolt 14, Figs. 1, 2, and 5, forlocking and positioning the width-wheel .occupies a socket at 15 in the free extremity of an arm 16, which is fitted to the free end of the stud 7 its beveled extremity entering the holes 1 11 in the web of the width-wheel as the said holes successively are caused to register with the said pin or bolt by the rotary movement of the width-wheel. The said arm 16 is provided at its inner extremity with a transverse groove 17, Fig. 5. to receive radial projections 18 18, Figs. 3 and 5, on the end of the stud 7. By the engagement of the arm with the said projections 18 18 the arm 16 is locked from change of position, being held from rotating with the width-wheel, and the said armis secured to the end of the said stud by means of a bolt or screw 19, Figs. 1, 2, and 5, having a flanged head which fits against the outer side of the arm, the stem of the said bolt passing through an eye 20 in the arm-and the said stem being screwed into a hole 21, Fig. 3, that is tapped in the outer extremity of the stud.

The means by which the operative is enabled to rotate the size-wheel intermittently to present the size-numerals upon its periphery successively at the printing-point comprises the ratchet-wheel 22, Figs. 3, 4, and 5, fast with the sizewheel, the pawl 23, engaging with the said ratchet-wheel, and the pawlcarrier 24:, the said pawl-carrier being in the shape of a lever, which is pivoted to the carrier 1 upon the stud 251, Fig. 3, the pivotal ing the pawl-carrier in its movements. The pawl 23 is mounted upon the side of the pawlcarrier on a stud 3'1, projecting from the pawlcarrier, and its tail has connected therewith one extremity of a tension-spring 310, the

other extremity of the said spring being conleave the half-size marker free to be moved nected with a small stud 32 on the pawl-earment with the ratchet-wheel. For the purpose of arresting the size-wheel from overrunning. when operated to shift the same by i movement suddenly or forcibly applied to the pawl-carrier the said pawl-carrier is furnished with a locking-pin 33, Figs. 3, .1:, and 5, projecting therefrom into position to engage with the locking-wheel 3 T, made fast to the sizewheel and having teeth or projections 35 with intervening depressions or notches 36, which successively receive the said locking-pin 33. Thus when the pawl-carrier 2% is depressed the engagement of the pawl 23 with the ratchetwheel 22 shifts the size-wheel one step, and at the completion of therequired movement of the size-wheel the said locking-pin 33 ent of the said head of the pin or bolt 44 in one ters one of the notches or recesses 36 of the locking-wheel 3% and by its engagement with the succeeding projection or tooth 35 arrests the rotary movement of the size-wheel. \Vhen the pawl-carrier is permitted to rise into its normal position under the influence of its-elevating-spring 37, Fig. 4, the size-wheel is retained in position by the spring-actuated pin or bolt 8. The elevating-spring 37 for the pawl-carrier is contained in a socket 371, 4, bored in the carrier 1, the said spring acting against a pin or bolt 38, which contacts by its outer end with the under side of the pawl-carrier adjacent the pivot of the latter. For the purpose of limiting the upward movement of the pawl-carrier a stop-pin 39 is applied to the carrier, the said stop-pin passing through a hole 391 made in the pawl-carrier.

The stop-wheel 3a is larger in diameter than the ratchet-wheel 22, as shown in Figs. 4 and 5, and is located between the said ratchetwheel and the web of the size-wheel 2, both of said wheels being fast upon the laterallyprojecting sleeve or hub 4:1 of the size-wheel 2 and both of the said wheels being covered by the laterally-prejecting flange or rim 25 at the periphery of the size-wheel. The arm 16 and its appurtenances are in similar manner contained within and protected by the outwardly-extending flange 42, forming part of the hub of the width-wheel 3.

For the purpose of limiting the half-size marker in its movements, and thereby determining the positions of the same at the opposite extremes of such movements, the body of the half-size marker is formed with a slot, as 43, Figs. 3 and 5, through which passes the extended body or stem of the pivotal stud 251, on which the pawl-carrier 2et is mounted. Stud 251 is represented as partly broken away By the action of the said spring the 1 working end of the pawl is kept in engage- E half-size marker into working position and in Fig. 5. The said body of the half-size marker is furnished with a handle 2&1, Figs. 1, 3, and 5, for convenience in moving the same by hand.

In order to couple or clutch the half-size marker to the size-wheel in such manner as to by hand independently of the size-wheelas, for example, when it is desired to throw the yet enable the size-wheel when advanced for the purpose of presenting a different size-numeral at the printing-point to cause the said half-size marker to move in unison with the size-wheel, and thereby restore the half-size marker to its normal or inoperative position-I employ in the present embodiment of the invention the yielding clutch comprising the pin or bolt AH, Figs. 3 and 5, occupying a ehamber45 in the body of the half-size marker and backed up by a spring e6, Fig. 6, which tends to project the head of the said pin or bolt beyond the side of the half-size marker and into one of the holes or recesses 4:41, Figs. 3 and 5, of the size-wheel. The engagement of the said holes or recesses is sufficient to enable the size-wheel when moving to carry the half-size marker backward from its working position, the half-size marker moving in unison with the size-wheel until arrested by contact of the end of its slot 43 with the stud 251. by which time the advance of the size-wheel occasioned by the depression of the pawl-carrier will also have terminated. So long as the half-size marker occupies its retracted position, being held from further movement by the contact of the end of its slot with the said stud 251, the advancing movements which may be communicated to the size-wheel will merely cause the coupling pin or bolt to yield, so as to permit the size-wheel to slip by.
